摘要
Provided is carbon material filler for an electromagnetic shield, which includes a graphitizable carbon material to be mixed into a molding material in order to absorb electromagnetic waves, the carbon material filler for an electromagnetic shield satisfying (1) to (3): (1) A spacing d002 of a 002 plane of the graphitizable carbon material measured through X-ray diffraction measurement (XRD) is at least 0.338 nm. (2) A relative intensity ratio (A/B) value between a peak intensity (A) of a “002 plane” detected when the graphitizable carbon material is measured through X-ray diffraction measurement (XRD) and a higher peak intensity (B) that is selected from a “100 plane” and a “004 plane” is at least 2.5 and less than 27. (3) The filler is in powder form and the average particle diameter D50 is at least 1 μm and at most 5 mm.
